TROLLEY-WHEEL.

Application filed May 8, 1916.

To all whom it may concern:

Be it known that I, VINCENT K. JOHN- SON, a citizen of the UnitedStates, residing at Indianapolis, in the county of Marion and State ofIndiana, have invented certain new and useful Improvements in Trolley-Wheels, of which the following is a specification.

This invention relates to trolley wheels and the object is to provide awheel adapted to remove ice and sleet rapidly from the wire, and tocause the resulting accumulation of broken ice and slush to be drainedout of the wheel and discharged by centrifugal action instead of packingand refreezing in the recesses to negative the ice and sleet removingeificiency of the device.

I accomplish the objects of the invention by the mechanism illustratedin the accompanying drawing, in which-- Figure l is a side elevation andpartial section on the line 22 of Fig. 2, of a trolley wheel embodyingmy invention and Fig. 2-

is a front elevation and partial section of same on the line 11 of Fig.1.

I have shown a wheel comprising a hubportion 3, having a central hole4:, for the usual stud on which such wheels are mounted. Integral withsaid hub is a web 5, and surrounding the Web is an integral rim (3, withan annular groove 7 to receive the wire.

A multiplicity of clearing spaces 8 are formed through both flanges ofthe rim, but without extending clear out, thereby forming radialspoke-like members 9, the outer ends of which are connected by narrowrimportions 10. The clearing spaces extend toward the hub past'thebottom of the groove 7 forming the latter into a ribbed surface. Thesides of the resulting ribs are beveled, the bevels extending from onerim-portion 10 on one side of the wheel to the rim-portion on the other,producing an edge 11 at their junction which contacts with and breaksthe ice and sleet on the wire, as the wheel is drawn forward in contactwith it.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Serial No. 96,258.

As the web 5 is very much less in thickness than the width of the rim 6,the clearing spaces 8 enable the broken ice and slush to escape from thegroove 7 through them, and any tendency for this discharge to pack andfreeze and to clog the clearing spaces is further obviated by 'bevelingthe web 5 where it crosses said spaces.

In the operation of my device the ice and sleet will be cut .and brokeninto small pieces and these will be forced by the wire through theclearing spaces and then thrown oif by the rotation of the wheel. Thebeveled portions of the web cut the wire strippings in two and help toprevent packing by enlarging the discharge outlet.

Having thus fully described my invention what I claim as new and wish tosecure by Letters Patent .of the United States, is

1. In a trolley wheel, a web,- a rim extended laterally on bothsides ofthe web, said rim comprising a pair of flanges separated by an annulargroove which receives the wire, said rim beingperforated by a pluralityof clearing spaces which extend through both flanges of the rim and alsoradially of the wheel past the bottom of said annular groove formingtransverse ribs in the grooved rim, said ribs being longitudinallybeveled on both sides and the web of the wheel being reduced inthickness to form annular clearance channels opposite the major portionsof said wire-receiving groove.

2. In a trolley wheel, a web, a rim extended laterally on both sides ofthe web, said rim comprising a pair of flanges separated by an annulargroove which receives the wire, said rim being perforated by a pluralityof clearing spaces which extend through both flanges of the rim and alsoradially of the wheel past the bottom of said annular groove formingtransverse ribs in the grooved rim, said ribs being longitudinallybeveled on both sides and the web of the wheel being reduced inthickness to form annular clearance channels opposite the major portionsof said Wire-receiving groove and the Web Where it crosses the clearingspaces being additionally reduced in thickness on two opposite sides toform ice cutting Wedges at the mid-lengths of said transverse ribs underthe middle of the downwardly pressing Wire and guides to direct the cutice-pack into said annular clearance channels.

In Witness whereof, I have hereunto set my hand and seal atIndianapolis, Indiana, this 26th day of April, A. D. one thousand ninehundred and sixteen.
